I managed to fit my road morph pump behind the seat tube. I have fenders so it can't end up rubbing the tire. That keeps my top tube free for shoulder carries and doesn't impact the bottle cages. I recently bought a Topeak Pocket Rocket DX (saves 4 oz over the road morph) and managed to fit it in the same bracket behind the seat tube. I still carry the road morph for tours and long rides.
Oil is good, grease is better.
